Abstract

Integration of carbosulfan (Marshal 25 ST) at 3% w/w; carbofuran (Furadan 3G) at 1kg a.i/ha; imidacloprid (Magik 70WS) at 2g/100g seed; profenophos (Carina 50EC) at 1 kg/ha along with organic inputs like FYM at l0t/ha, neem cake at 200 kg/ha; NSKE 5%; NSKE 1% and mustard oilcake at 100 kg/ha against root knot nematode, Meloidogyne incognita, fruit borer, Earias vittella and other insect pests of okra. The results of two seasons revealed that application of carbosulfan as seed treatment followed by application of neem cake and soil application with carbofuran provided significant control of root-knot nematode and fruit borer in okra. Imidacloprid at 2g/100g seed as seed treatment alongwith neem cake as soil application at 200 kg/ha proved to be best in reducing populations of white fly, Bemisia tabaci, jassid, Amrasca biguttula biguttula and Earias vittella population. Leaf defoliation due to Spodoptera litura was significantly reduced in plots treated with mustard oilcake at 100 kg/ha followed by spraying with profenophos at 1kg a.i/ha in both the seasons. Thus, seed treatment with carbosulfan at 3%w/w or imidacloprid at 2g/100g seed followed by neem cake at 200 kg/ha and or carbofuran 3G at 1kg a.i/ha as soil application could be recommended to manage insect and nematode pest problems of okra.
